Chromium: same page, same machine, idle, Firefox 24.2% of a core against Chromium's
11.4%. The build comes from archive.raspberrypi.com (a "+rpt" version) and is patched
for this board's V3D GPU; Debian ships a much older chromium, so the archive matters.
The whole userland here is 32-bit armhf on a 64-bit kernel, which Firefox handles worse
than Chromium does. --use-gl=egl, --enable-gpu-rasterization, --ignore-gpu-blocklist
and --enable-zero-copy are what keep rasterization on the GPU: Chromium's blocklist
does not recognise this driver and silently falls back to software without them.
pi_kiosk_browser: firefox still works, as the fallback if an update ever regresses.
Debug mode also gains xdotool, scrot and --remote-debugging-port=9222 (on 127.0.0.1),
because firing XTEST key events at a window lands about half the time and a benchmark
you cannot verify the state of is worse than none.
pi_squeezeserver gains an absent path, and mediapis.yml derives its state from
mediapi_has_squeezeserver, which defaults to false for the whole group. false means
"actively remove", not "skip": musicdolphin has been running a Logitech Media Server
that no playbook installs and nothing talks to - every squeezelite in the fleet points
at pi_squeezelite_squeezeserver (192.168.178.80, the server) - while costing ~30 MB
resident and ~47 MB of swap on a 2 GB Pi that also drives the kiosk. The absent path
stops it, purges the package, unregisters it from sysdweb, drops the port 80 -> 9000
redirect and deletes its database and logs.

The role ran no window manager on the theory that Firefox is the only X client and
--kiosk makes it full-screen by itself. It doesn't: --kiosk *asks* to be full-screen
over EWMH, and with no WM running nobody answers. Firefox kept its default window
size in the top-left corner - on musicdolphin's 1920x1080 monitor, a 1280x972 window
with black bands down the right edge and along the bottom, which looks exactly like
an overscan problem and isn't one. Openbox answers the request and does nothing else.
pi_kiosk_mode=debug then turns the attached screen into something workable: Firefox
as an ordinary window that is not relaunched when you close it, a visible pointer,
Openbox as the session leader with a root menu offering a terminal, and xterm,
x11-utils and mesa-utils installed. musicdolphin is set to debug for now.
The templates notify the getty handler, so a mode switch restarts the session on its
own - Xorg lives in that unit's cgroup.

The app grew a python-backend/ and a web/ frontend, so pi_musicmouse no
longer matches it. Rework the role:
- Install a pinned uv and build the venv with Python 3.13; Raspbian
Bookworm's python3 is 3.11 and the backend uses PEP 695 syntax.
- pip install python-backend/ instead of a requirements.txt, and take
the systemd unit straight from the checkout so it can't drift.
- Build web/ on the control machine (no npm on the Pi) and rsync
web/dist over. Chain the checkout -> install -> build -> sync -> restart
steps through handlers so a run with no repo change does nothing.
- Per-host config files (config-<host>.yml); the schema now differs
between a host with a real mouse and a display-only one.
- Version to deploy is per host (musicmouse_version), no default.
Add pi_kiosk: autologin user running startx with Firefox in kiosk mode
and no window manager, for a Pi with a monitor attached. Enabled by
mediapi_has_monitor, defaulting off.
Turn musicdolphin into a display-only instance: serial and audio
simulated, driven entirely through the kiosk page.
